This paper is intended as performance verification of efficient container door Open/Closed detection mechanism for Container Security Device(ConTracer) to container cargo transportation. Container door Open/Closed detection mechanism using Reed sensor is important to satisfies the US Department of homeland security customs and border protections requirements to many types of container door. Also, Verify that the container door is configured correctly and that you can check the illegal opening. In this article, Performance valuation of this Contacer on reed sensor has been verified through field test for each other 30 containers. Once the improvement has been made, we are suggest that propose skills will meet the highest standards for container security safety.

RFID 기술은 유비쿼터스 사회로 가는 첫걸음으로 인식되면서 많은 연구와 활용방안이 논의되고 있다. 항만 물류의 화물 컨테이너 보호 분야도 그 좋은 예이다. 즉, 화물 컨테이너를 안전하게 잠그고 열며, 화물 정보를 보호하기 위한 전기적 잠금 장치로써 RFID 기술이 활용될 수 있다. 본 고에서는 화물 컨테이너 운송의 안전성을 지원하기 위한 국제 표준화 현황을 살펴보고, 실제 상용화에 박차를 가하고 있는 대표적인 RFID 장치인 전자봉인(eSeal)과 컨테이너 보안장치(CSD)의 기술적 특징에 관하여 논한다. 본 고에서의 주요 관심은 전자 장치로서의 화물 컨테이너 보호용 RFID 태그와 리더 기술이며, 특히 화물 컨테이너의 중요 데이터를 보호하여 컨테이너 운송 시스템의 효율성과 보안성을 동시에 향상시킬 수 있는 데이터 보호 요구사항을 정리하며 결론을 맺는다.

Container Security Device (ConTracer) which is suggested in this study is to monitor temperature, humidity, and impact inside of the container while the container is transported. ConTracer could also give information to users when a door of the container is opened over 2 inch within 1 second. Additionally, GPS/GLONASS based global position and status information about container are transmitted to a remote server using IoT (Internet of Things) based communication. In this research, we are looking into the development trend of global container security devices; and applying ConTracer to real freight transport from domestic to overseas using Global Roaming Service which is offered for domestic Mobile Communication Companies as well. As a result, we estimate the performance of ConTracer and verify it.

CSD is IEEE Stan없rd 802.15.4b based Container Security Device which is proposed by the U.S Department of Home Security. It is mounted inside the container to sense opening of the container door. ConTracer is the CSD which is developed in this research whose major features are sensing door opening status as well as history inquiring on internal environment and shock to the container by mounting the temperature/humidity/shock sensors. Moreover, its RFID frequency bandwidth uses 2.4GHz 10 correspond actively to the radio regulations used by different countries. This. paper introduces the development trend of CSD, compares the ConTracer which is developed thru this research and other company's CSD, and introduces CSD System which is designed and established using ConTracer. Finally, the implemented CSD System is verified by applying the demonstration service to container distribution between Korea and Japan.

CSD(Container Security Device) is a security device with sensors that can detect the abnormal behavior such as illegal opening of a container door. Since the CSD provides security and safety of the container, CSD should not only provide security services such as confidentiality and integrity but also cloning detection. If we can not detect the cloned CSD, an adversary can use the cloned CSD for many illegal purposes. In this paper, we propose a policy based cloned CSD detection mechanism. To evaluate proposed clone detection mechanism, we have implemented the proposed scheme and evaluated the results.

In this paper, A Design of 2.45GHz and GPS antenna Integrated Board using Container security Device(ConTracer) for container cargo transportation is proposed and experimentally evaluate. Integrated antenna board include 2.4GHz chip and Ceramic GPS antenna is also consider the impact of RF interference based on simulation for applied to steel container. After a careful comparison and analysis a part of the container door for its best performance, We conduct tests to characterize. The proposed integrated antenna board is suitable for container cargo transportation application in steel container field.

컨테이너 보안장치는 컨테이너 문에 부착하여, 문의 개폐 여부를 전자적 신호를 통해 수집하는 장치이다. 이와 관련하여 국제표준화기구의 ISO18185를 통해서 관련 내용이 다루어진다. ISO18185를 기반으로 여러 업체에서 다양한 컨테이너 보안장치를 제조하고 있으며, 대표적으로 savi사의 e-Seal이 있다. 표준에서 제시한 CSD는 리더를 통해 통신하여 상위 프로그램에게 정보를 제공한다. 그러나 이는 리더가 없는 지점에서는 CSD의 정보를 알 수 없다는 단점이 있다. 그래서 WCDMA 통신을 통해 주기적으로 자신의 상태를 보고하는 CSD가 개발중이며 본 논문은 주기적으로 자신의 정보를 전송하는 WCDMA기반 CSD와 리더기반 CSD를 동시에 지원하는 플랫폼 설계 및 구현을 다루고 있다.

CSD is Active RFID based Container Security Device which is proposed by the U.S Department of Home Security. It is mounted inside the container to sense opening of the container door. ConTracer is the CSD which is developed in this research whose major features are sensing door opening status as well as history inquiring on internal environment and shock to the container by mounting the temperature/humidity/shock sensors. Moreover, its RFID frequency bandwidth uses 433MHz and 2.4GHz to correspond actively to the radio regulations used by different countries. This paper introduces the development trend of CSD, compares the ConTracer which is developed thru this research and other company's CSD, and introduces CSD System which is designed and established using ConTracer. Finally, the implemented CSD System is verified by applying the demonstration service to container distribution between Korea and China.

A Container Security Device (CSD) which is different existing RFID Tag strengthens the physical security as mounted inside the container and the information security as encrypts doubly a data. CSD must use the resources efficiently in order to operate with the battery. Therefore, it needs low-power mechanism which repeats the sleep period and channel scan period. However, by adjusting these periods, the trade-off occurs between energy efficiency and network connectivity. In this paper, we implement low-power CSD and resolve this problem by adjusting beacon period and channel scan time. As a result, We guarantee the network connectivity 95% or more and maximum life up to 16 days using common AA batteries.
